Every professional from the Software Testing & Quality Assurance domain is obviously mindful of HP's LoadRunner.

LoadRunner can be a well-known next-gen performance verification & validation tool brought by HP. That is a unique tool in which we can easily simulate situation with hundreds or a large number of artificial users & can impose definite, consistent and repeatable loads around the system thereby stressing it from end-to-end.

LoadRunner is made to accurately predict the particular performance and behavior from the application, thereby increasing our confidence from the reliability of the modern system before it gets actually deployed.

A beginning has been given to bring out a self-learning / Training series wherein the aspirants can Learn & Master LoadRunner through High Quality Question Answers. Using a mastery during these Question Answers on LoadRunner, one can feel safe for this vast topic, while facing interviews as well, in a leading MNC.

Handful of such Question & Email address details are presented below:

Q. 1: What's the aim of using HP - LoadRunner?

In actual world scenario, it's not necessarily very easy to create situation involving say thousands of users employing a system simultaneously so that you can test the behavior from the system under such stressful conditions. LoadRunner can cause this sort of situation.
LoadRunner artificially simulates thousands of users - which might be called Virtual Users. These artificial / digitally created users are simultaneously made to run on the identical task, thereby loading the machine in a way it can be likely to be loaded by real human users in actual practice.
With LoadRunner we can easily simulate situation with hundreds or a large number of artificial users & we can easily impose definite, consistent and repeatable loads around the system thereby stressing it from end-to-end. That way we can easily emulate several business processes & production conditions, that your deployed application is likely to encounter.

Q. 2: What are essential capabilities we look in the typical application performance-testing Tool?

Essential capabilities of an application performance testing tool are that:

1) It should be capable to test a process which combines many programs and hardware platforms.
2) It should be capable to determine the suitability of an server for just about any given application.
3) It should be capable to test the server prior to the necessary client software continues to be developed.
4) It should be capable to emulate a place where multiple clients communicate with an individual server application.
5) It should be capable to test a credit card applicatoin beneath the load of tens, hundreds, and even a large number of potential users.

Q. 3: What are drawbacks of manual load testing processes?

Load testing of an complete system is possible manually by building a place where many users work simultaneously around the system. Each user is made to work with his standalone machine and every individual submits input to the system. However due to complexity for these a process, following drawbacks will there be

1) Manual testing methods just offer a partial means to fix the load testing.
2) Manual testing is expensive & requires large amounts of manpower & equipment.
3) Manual testing is complicated, especially while coordinating and synchronizing multiple testers.
4) Manual testing involves a top degree of organization, especially to record and analyze results meaningfully.
5)The repeatability from the manual tests has limitations.
